I don't believe so (mind you, my last rounds were circa 2015 and
Kenalog wasn't ever mentioned by name, at least as far as my memory serves). If it was used, it was used at most minimum since my understanding was that they felt they could go under the skin and loosen up the clumping of collagen or fibrotic matter via cannula).
Some nodules (especially the wider softer ones) went away on their own. The small "rice" or "pellet" sized ones could be removed through punch excision. I feel like
Kenalog, DMSO, and more aggressive interventions belong to generally more troublesome nodules and irregularities that can't be resolved through conventional means.
Then again I haven't dealt with these types of revisions for a decade and the conventional wisdom in regards to how these are solved as best asked directly to the Doctor who will be treating the patient who requires said-intervention. I hope to update the site's Wiki/Q&A to have more up-to-date info on these kinds of topics.
